# Testing by image size or ad label

This type of test is best for image ads in Google Display campaigns. It allows you to see which creative or ad size performs better based on your preferred metrics. 

### **How are the tests set up?** <a href="#how-are-the-tests-set-up" id="how-are-the-tests-set-up"></a>

You can run the tests and see results instantly. Alternatively, you can set them to run daily. For example, if you're not satisfied with the statistical significance of your instant results, it may make sense to run them again.

#### **Instant test results**&#x20;

1. Go to **Ad testing** > **Multi ad group** > **Test image ads.**
2. Select your campaigns and the date range for this test. A common date range means Adalysis will calculate a date range during which all ads within the test were active.
3. Specify the ad labels you want to use for comparing your ad performance. You can also exclude ads in the **Label contains none** column.&#x20;
4. Select the banner sizes you want to compare. You can use only labels, or only sizes, or combine the two.&#x20;
5. Click **Find current winners**. &#x20;
6. If you want Adalysis to run this test automatically, click **Save & run this test daily**.

#### **Daily test runs**&#x20;

We’ll alert you via your Adalysis dashboard once statistical significance is reached. You can save your test as described above or from **Daily results of your defined tests**.

### **Understanding the test result data** <a href="#id-3-understanding-the-test-result-data" id="id-3-understanding-the-test-result-data"></a>

You'll see the test results in the grid. Once you open the test result details, you will see the aggregate performance of each label/size (over the date range used) and the confidence the algorithm has in each of the metrics. &#x20;

You'll also see performance boost projections based on pausing all losing ads.&#x20;

### **Bulk actions** <a href="#id-4-taking-action" id="id-4-taking-action"></a>

After viewing individual test results, you can pause the losing ads with a single click.&#x20;

Once you pause the ads, the test is marked as archived and you can always find it under the **Archived test results** tab.&#x20;

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.adalysis.com/tools/ad-testing/multi-ad-group-testing/testing-by-image-size-or-ad-label.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
